                             Recommended cash offer

                                      for

                                 Transcomm plc

                Level of Acceptances and Extension of the Offer

British Telecommunications plc ("BT") announces that, as at 3.00 p.m. on 8 March
2004, being the second closing date of the Offer, valid acceptances of the Offer
had been received in respect of a total of 86,820,254 Transcomm Shares,
representing approximately 84.44 per cent. of the issued share capital of
Transcomm. The Offer has been extended for a period of 7 days and will,
therefore, remain open for acceptance until 3.00 p.m. on 15 March 2004.

Transcomm Shareholders are advised that if the acceptance condition of the Offer
is not satisfied by 3.00 p.m. on 15 March 2004, BT might not extend the Offer
beyond 15 March 2004, in which case the Offer would lapse. However, BT reserves
the right to extend the Offer, should it wish to do so.

On 23 January 2004, BT announced that it had received irrevocable undertakings
to accept the Offer in respect of 49,652,107 Transcomm Shares, representing
approximately 48.3 per cent. of the issued share capital of Transcomm.

Neither BT, nor any person acting, or deemed to be acting, in concert with BT
for the purpose of the Offer owned, or controlled, any Transcomm Shares or any
rights over any Transcomm Shares immediately prior to the commencement of the
Offer Period. Neither BT, nor any person acting, or deemed to be acting, in
concert with BT for the purposes of the Offer has acquired or (other than
pursuant to the Offer) agreed to acquire any Transcomm Shares or (save for the
irrevocable undertakings to accept the Offer referred to in the announcement by
BT on 23 January 2004) any rights over any Transcomm Shares during the Offer
Period. None of the valid acceptances referred to above have been received from
persons acting in concert with BT.

Transcomm Shareholders who have not yet accepted the Offer and who wish to do so
are strongly encouraged to complete and return the Form of Acceptance (whether
or not their Transcomm Shares are held in CREST) as soon as possible and, in any
event, so as to be received by post or (during normal business hours) by hand by
Lloyds TSB Registrars plc, Princess House, 1 Suffolk Lane, London EC4R 0AX by no
later than 3.00 p.m. on 15 March 2004.
